Please answer my questions as they are spelled out:  

1.  If I ordered 35 miners from you, paid for them in bitcoin, would you run a background check on me (due diligence) and require me to provide collateral in excess of $100k?  If not, why?
2.  What is the collateral you are holding?  Is it Bitcoin, Euro, Dollars, or?  The "over 9000" is not an answer.
